When charging, there is an indicator – Green for when it is fully charged, Red for Charging

Easy to hold light, fits good in the hand.

The switch is angled and is comfortable to use and switch levels.

Overall tons of good features, good solid performance out of the light, and you can get a few good minutes of 2500 lumens.

Cons :

…

I’ve discovered that this headlamp isn’t compatible with all 18650 batteries, some it will work with and some it will not. What it is that makes the difference, I don’t know. Olight claims that their batteries are customized but I don’t know how that has been done specifically. They look no different than any of my other 18650 batteries.

There are a lot of pieces and components to this light and it would have been nice if the company would have included at least a carry bag to keep everything together. Some of Olights other products come with such cases.

Odd stepping between levels – I would like to see a 1000 lumens mode as it is hard to tell the difference between 600 and 300 lumens.
